That's why EU laws to punish such negligence are a good thing. They increase the risk for companies, to something very specific.
GDPR has put some fear back in, but even today there are loads of companies that simply don't give a shit, and will happily risk it all so that they don't have to adapt their practices from years ago. In my experience, smaller companies are the worst offenders, because they know they are small fry.
Pipdig are a UK company, and have been actively caught using malicious code with proof, yet they're still running without a care in the world. This all happened recently too, so it's not like it's a pre-GDPR or pre-ICO crackdown issue.
